A first characteristic, calculated in respect of a first time period, and a second characteristic, calculated in respect of a second time period, are used to extrapolate a measured characteristic, measured over the first time period, to determine a determined characteristic for the second time period. | 06-12-2014 |
20140306780 | Duplexers - An electrical balance duplexer comprising an electrical balance load having an electrical balance load connection, an antenna connection, a first differential power amplifier output connection, a second differential power amplifier output connection; and a power combiner configured to combine output power signals from the first differential power amplifier output connection with output power signals from the second differential power amplifier output connection into the antenna connection and into the electrical balance load connection. | 10-16-2014 |

20110123879 | METHOD AND ARRANGEMENT TO REDUCE THE CONSUMPTION OF SAFETY GAS IN A FUEL CELL SYSTEM - A method and system are disclosed for reducing the consumption of safety gas in a fuel cell system having at least one fuel cell unit whose fuel cells include an anode side and a cathode side, as well as an electrolyte interposed therebetween. A supply is provided for supplying the anode with a safety gas, and an exhaust is provided for exhausting the fuel cell unit of a spent safety gas coming from the anode side. The method can adapt a specific percentage of the spent safety gas flow coming from the anode side of the fuel cells to be re-supplied into the anode side of the fuel cells. | 05-26-2011 |
20110165486 | METHOD AND A CONTROL ARRANGEMENT FOR A FUEL CELL DEVICE - The disclosure relates to a fuel cell device arrangement for producing electrical energy, having at least one fuel cell anode and cathode, an electrolyte for conveying ions between the anode and the cathode, and a passage separate from the electrolyte for the electrons travelling from the anode to the cathode. A control arrangement can prevent the formation of carbon by calculating a thermodynamic equilibrium model based on thermodynamic equilibriums of chemical reactions for the feedback recirculation of fuel. Measurement values are obtained, at least from the electric current and the fuel flow rate, for calculating the fuel composition. Conversion values set on the basis of the thermodynamic equilibrium model for the fuel are calculated using the measurement values and fuel composition. The calculation can be repeated to produce the conversion values by which the fuel composition can be determined to converge with sufficient accuracy, so that operation of the fuel cell device can remain within safety limits according to the thermodynamic equilibrium model. | 07-07-2011 |
